Description
HEPS (High Energy Photon Source) will be the first high-energy (6 GeV) synchrotron radiation light source in China, which is mainly composed of accelerator, beamlines and end-stations. Phase I of the project includes 14 user beamlines and one test beamline. Construction of HEPS began in June 2019 and is scheduled for completion in late 2025. Meanwhile, beamlines have completed photon beam commissioning, marking HEPS' official transition to the joint-commissioning phase, starting from March 27th, 2025. The beamline controlled devices are mainly divided into two categories: one category is optical adjustment devices such as slits, K-B Mirrors, monochromators, etc.; the other category is optical diagnostic and detection devices such as XBPMs (X - ray Beam Position Monitors), fluorescence targets, detectors, etc. The beamline control system has been designed, based on the EPICS framework. Beamline network topology consists of three networks, namely the data network, control network, and equipment network. In order to enhance the software reusability and maintain version uniformity, package management technology is utilized to manage both application software and system software. Here, the design and construction of beamline control system are presented.
